Are You Safe From a Death Ray?

There's this past light cone that dictates all the things that could be influencing what's happening at your location. And somebody really far away, or even a foot away, can't influence what's happening to you right now. But if they shot it a million years ago, it would be hitting us right now - potentially. It just means that somebody's got a plan ahead if they really want to fry us. Now, they con either be hoby or havt plan ahead. Man, dislike ond makes me feel not at all safe.
